The present disclosure describes systems and methods that employ a plurality of microwave applicator cells as a combined unit to continuously travel along an asphalt surface to treat the existing asphalt with microwave energy. The microwave treatment reanimates the existing (and likely damaged) asphalt to a workable state that is almost identical in nature to newly laid asphalt. The microwave system is configurable to span the width of a standard road lane, wherein the continuously traveling system efficiently repairs damaged roads with minimal down time.

This invention discloses a flexible microwave radiator and magnetic detection system for magnetic detection of NV centers in diamond. The flexible microwave radiator includes a flexible dielectric substrate and a conductive layer disposed on the substrate. The conductive layer is patterned to form a power supply area and a radiation area electrically connected to the power supply area. The power supply area is used to connect a microwave signal source, and the radiation area has a through-hole penetrating the flexible dielectric substrate. The flexible dielectric substrate is bent at the position corresponding to the radiation area towards the side opposite to the conductive layer to form a bend. The radiation area and the through-hole bend along with the bend, and the bend allows it to approach the diamond containing NV centers from the side, enabling the through-hole to apply microwave radiation to the NV centers of the diamond from the side. This invention can ensure that the microwave radiator is close to the diamond for microwave coupling while reducing the obstruction of the excitation light and fluorescence collection light path above the diamond, thereby improving fluorescence collection efficiency, system signal-to-noise ratio, and magnetic detection sensitivity.

This utility model relates to the field of medical device technology, and in particular to a microwave radiator for lumbar physiotherapy, comprising a body, cables, a radiating head, and a fixing mechanism. The fixing mechanism includes a bracket, an adjustment component, a power component, two sliding plates, two fastening components, a male Velcro strap, and a female Velcro strap. The radiating head is mounted on the bracket via the adjustment component. The bracket has a sliding groove, and both sliding plates are slidably connected to the groove. The two fastening components are fixedly connected to their respective sliding plates. The male and female Velcro straps are connected to their respective fastening components. The power component drives the two sliding plates to move relative to or towards each other within the groove. This method solves the technical problem in the prior art where patients cannot move freely during physiotherapy, and even slight movement can easily cause the microwave radiator to misalign with the affected area, affecting the treatment effect.
